Taillon was treated for suspected testicular cancer Monday, Stephen J. Nesbitt of the Pittsburgh Post-Gazette reports.
This awful news comes after Taillon was placed on the disabled list with groin discomfort Saturday. A timetable for return obviously remains uncertain at this point, as his health and well-being remain the No. 1 concern. Trevor Williams is occupying Taillon's spot in the rotation for the time being, though it's unclear whether he'll continue to do so in the case of an extended absence. Here's hoping everything comes out well and he works toward a speedy recovery.
